Answer:

x =12

Step-by-step explanation:

We use the Pythagorean theorem

a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse

x^2 + 5^2 = 13^2

x^2 +25 =169

Subtract 25 from each side

x^2 +25-25=169-25

x^2 = 144

Take the square root of each side

sqrt(x^2) = sqrt(144)

x = 12

Answer: 12

Step-by-step explanation:

13 times 5 = 56

then divide 56 by 2

=12

x^2 +25 =169

Subtract 25 from each side

x^2 +25-25=169-25

x^2 = 144

x = 12

hope this helps :)

Using the Binomial Probability table, find P(X) when n = 7, X < 3, and p = 0.5 A. 0.273 B. 0.500 C. 0.227 D. 0.773
Nat2105 [25]

Answer:

0.227

Step-by-step explanation:

Given that X is binomial with n=7 and p =0.5

To find the probability for P(X<3)

i.e. we have to find prob as =P(x=0,1,2)

=P(X=0)+P(X=1)+P(x=2)

P(X=r)=7Cr(0.5)^7

Using binomial table we find prob

P(X<3)=0.2265

Round off this to 3 decimals as

0.227

Hence answer is 0.227

Plane R contains which of the following?
mars1129 [50]

The letter R is on the yellow section, which indicates the yellow area is plane R.

Now see what points and lines are on the yellow sections.

Point M, point R, line F are all in the yellow area. Point X and Y are at the intersection of the two planes, so could be part of both.

Based on the provided answers, the answer would be: Point M and line f.

Part B: In complete sentences, explain how a circle can be used to find the circumcenter of the triangle graphed below.
Karo-lina-s [1.5K]

Answer:

Step-by-step explanation:

<u><em>Part B:</em></u>

The center of the circumscribed circle around a triangle is equidistant from vertices of that triangle. To find the circumcenter need to draw at least two perpendicular bisectors to the sides of the given triangle. Point of intersect of them is center of the circumscribed circle.

<u><em>Part C:</em></u>

Coordinates of the midpoint of line BC ( y = - 1 ) are

( \frac{-6+2}{2} , \frac{-1-1}{2} ) = <em>( - 2 , - 1 )</em> and the equation of the line ⊥ to BC is <em>x = - 2</em>

Because BC is ║ to x-axis and m∠A is 90° , the center of the circle is midpoint of BC and r = \frac{BC}{2} = 4
